Photoacid generators (PAGs) based on N-acyl-N-phenylhydroxylamines for carboxylic and sulfonic acids

Mohammed Ikbal, Avijit Jana, N. D. Pradeep Singh* and Rakesh Banerjee, Dibakar Dhara*
Abstract: Simple and efficient photoacid generators (PAGs) for carboxylic and sulfonic acids based on N-acyl-N-phenylhydroxylamines have been demonstrated. Irradiation of o-carboxylates and thermally rearranged o-arenesulfonates of N-acyl-N-phenylhydroxylamines using UV light (≥254 nm) in...

Development of 1-Hydroxy-2(1H)-quinolone based photoacid generators and photoresponsive polymer surfaces

Mohammed Ikbal, Rakesh Banerjee, Sanghamitra Atta, Avijit Jana, Dibakar Dhara*, Anakuthil Anoop* and N. D. Pradeep Singh*[a]
A new class of carboxylate and sulfonate esters of 1-hydroxy-2(1H)-quinolone has been demonstrated as non-ionic photoacid generators (PAGs). Irradiation of carboxylates and sulfonates of 1-hydroxy-2(1H)-quinolone by UV light (≥310 nm) resulted in homolysis of weak N-O bond leading to the...
